Which function of Cain is said to work over WAN? Basically Cain is used for Netbios accesses, sniffing and cracking. None of these functions will work in a routed network. That's why there are VPN's and FTP's
Theoretically Netbios works over TCP/IP, but I've never seen it so far

Yes, it will work over the internet, so long as you are running it from a Public IP (Not Dial UP). the remote PC has to have the NetBios Ports open on the internet as well, however, there are not many of them that have not already been hacked. I test hosts with this all of the time. Make sure you are hitting an actual host and not a router as cain wont connect ot a router the same way as a workstation.

hi i m new to hacking.i m using cain.but when i right click on user it gives user inumeration error-access denied.what could be the mistake..all lan connected pc are having same dns settings.plz help me

The reason that you get the access denied is because of a Group Policy setting that is preventing the enumeration of anon sids. You should go after the DC first, as many Admins are reluctant to set this setting on their domain controllers (or they dont know the difference between "Local", "Domain Local", and Domain Controller group policy settings. Additionally, if you will attempt this on every PC on the domain, you will surly find at least one pc that does not have this setting, if you do, then look to see if there is a user account on a workstation that has domain rights. From there you can log in as that user, then you will no longer be anon, and then you can enumerate the Sids and users.

thanks for your suggestion
but i cant find the computer of that kind in the network.But i want to see it working.so plz tell me the detailed step to configure two computers in a lan(not activating the allow user to connect remotely option).
say my computer is in domain MSHOME.so whethere i have to make the other pc in same domain that is MSHOME for the cain to give no inumeration error.plz tell in details.bcoz i m beginner and want to acquire detailed knowledge on networking.i think you wiil help me to achieve my goal

Start off by buying a CompTia Network Plus study book, then read it, then read it again. Then you will have a basic understanding of networking in a client/server infrastructure, the process in question will make a great deal more sense once you understand some basic concepts.

Also, if they are both your computers, then right clisk on the computer name and click, "Connect As", then enter your credentials, then go from there.

It seems like he already answered your question for you right there.

i havent understand ,what to set in group policy.where can i find group policy settings and what settings need to be done to have cain working on two lan connected pc.plz tell in such a way that a beginer like me can understand what u r trying to say. [ ]

Sniffing with Cain requires ARP
ARP is an OSI Layer 2 Protocol
To get from a Lan to a Wan requires passage through a Layer 3 device
Therefore, Sniffing of the WAN from a LAN is not possible "With Cain".

Move your Workstation to the WAN and you will be able to sniff all the traffic on the segment that you are plugged into.

the same here

any suggestions ?

another questions :

(1)

i can sniffing on my lan and see what sites another computer visits
but it seems am not able to crack the password for them ..it doesn't accept to be sent to cracker so how can i crack them .

(2)

i already done asniffing on voip calls , cain recorded averysmall part of call and it was the only one it succeeded to do it , other calls have problems to be recorded , cain saya " codec error " , so how to overcome this .

(3)

i tried to crack guest password and i sent it to cracker and craked it
but it says that it was successful and the password is :
then space .

The password is blank,
Cain has only limited Codec support as indicated on the web site,
The filters for extracting passwords are predefined, you can add options for the filter in the application if you look for it.

"Failed to retrieve error description" sounds like a problem on your computer.

To use Abel, you will need to have administrative access to the workstation or server that you are trying to connect to. Cain does have the ability to help you get access to the admin credentials, but you will need to play with the application a bit to figure out all of its features.

Keep playing, it will become clear as you learn both networking as well as the application.

As stated before, an understanding of the information contained in the CompTia Network+ certification track will prove invaluable in your quest.
